Question

您好，当我尝试执行 bundle exec rake db:migrate 时遇到问题 我从来没有遇到过这个问题，这是代码

bundle exec rake db:migraterake aborted!

这是我做的第一部分rails generate controller AccountActivations \ edit --no-test-framework

然后routes.rb

Rails.application.routes.draw do

  get 'account_activations/ edit'

  get 'account_activation/ edit'

  get 'sessions/new'

  root                 'static_pages#home'
  get 'help'        => 'static_pages#help'
  get 'about'       => 'static_pages#about'
  get 'contact'     => 'static_pages#contact'
  get 'signup'      => 'users#new'
  get 'login'       => 'sessions#new'
  post 'login'      => 'sessions#create'
  delete 'logout'   => 'sessions#destroy'
  resources :users
  resources :account_activations, only: [:edit] 
end

然后我运行这段代码：

$ rails generate migration add_activation_to_users \
> activation_digest:string activated:boolean activated_at:datetime

我修改了这个新文件

class AddActivationToUsers < ActiveRecord::Migration
  def change
    add_column :users, :activation_digest, :string
    add_column :users, :activated, :boolean, default: false
    add_column :users, :activated_at, :datetime
end end

最后是bundle exec rake db:migrate 然后我收到错误消息，有人看到任何问题吗？提前致谢！ 顺便说一下，这是第 10 章 ruby​​ on rails 教程。

Answer 1

我想你可能正在使用

resources :account_activations

错误...资源应该在模型上使用，在这种情况下它是一个控制器 -> 这就是您的日志所抱怨的。 这是您的一些参考：http://guides.rubyonrails.org/routing.html#resources-on-the-web

资源路由允许您快速声明给定资源控制器的所有公共路由。资源丰富的路由不是为您的索引、显示、新建、编辑、创建、更新和销毁操作声明单独的路由，而是在一行代码中声明它们。

也许运行一个

rake routes

查看您有哪些可用路由，以及“resources :account_activations”是否正在编辑路由。

Answer 2

可能只是删除这两行就可以解决它：

get 'account_activations/ edit'

get 'account_activation/ edit'

您已在此处和资源中定义了此路线两次。

Answer 3

您的routes.rb 错误。

Rails.application.routes.draw do

  get 'account_activations/edit'

  get 'account_activation/edit'

  get 'sessions/new'

  root :to => 'static_pages#home'

  get 'help'        => 'static_pages#help'
  get 'about'       => 'static_pages#about'
  get 'contact'     => 'static_pages#contact'
  get 'signup'      => 'users#new'
  get 'login'       => 'sessions#new'
  post 'login'      => 'sessions#create'
  delete 'logout'   => 'sessions#destroy'
  resources :users
  resources :account_activations, only: [:edit] 

end

Answer 4

help 和 about 路由缺少它的控制器（可选操作）参数。

root 路由也缺少它的选项。
